(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus64 kewx 211146 afdewx area forecast discussion national weather service austin san antonio tx 646 am cdt Wed aug 21 2019 Aviation At ksat kssf, MVFR CIGS mix out mid morning around 21 14z and return overnight into Thursday morning 22 08z-15z. At kaus, a southwesterly component to the lower level flow this morning and overnight into Thursday morning will keep MVFR level clouds few-sct, though will monitor for possible updates to mention cigs. Otherwise,VFR flying conditions will prevail. At the i-35 sites, southerly winds up to 8 kts back to southeasterly this afternoon, increase to 9 to 15 kts with a few gusts to 22 kts with the passage of the seabreeze this evening, then veer to southerly at 4 to 9 kts tonight. At kdrt, easterly winds 5 to 10 kts veer to southeasterly at 10 to 15 kts with a few gusts to 22 kts late morning into afternoon, then back to easterly at 5 to 10 kts this evening. Prev discussion issued 344 am cdt Wed aug 21 2019 short term (today through Thursday)... the upper level ridge of high pressure which has kept the area hot and dry for the last several days will begin to break down Wednesday into Thursday. While the trend of hot and mostly dry weather will continue temperatures will moderate slightly, with highs one or two degrees cooler than they have been. This will also mean that rather than 108-110 afternoon heat index values, heat indices for Wednesday and Thursday will run more in the 103-106 range. In addition to the slightly cooler temperature there will be slight chances for showers and thunderstorms each afternoon east of the interstate 35 corridor due to the coastal sea breeze. While coverage should be less than what was seen on Tuesday, a lucky few should get a brief break from the heat and some beneficial rain Wednesday and Thursday afternoons. Overnight lows will continue to run several degrees above normal, in the mid to upper 70s, while afternoon highs trend closer to normal, but remain one to two degrees above normal. Long term (Thursday night through Tuesday)... Friday will be similar to Wednesday and Thursday with afternoon highs in the upper 90s across much of the area, with triple digit heat closer to the rio grande plains. Models continue to differ with their |
solutions for Saturday and beyond. All 3 global models: gfs ECMWF canadian develop a low pressure system across northern mexico Friday night into Saturday morning. The 00z GFS remains the strongest with this low pressure system, having it catch the tail end of the trough dropping from the plains into the SE CONUS Saturday night into Sunday. The canadian is similar, but slightly slower than the GFS in terms of timing. The ECMWF is the weakest with this low pressure system and leaves it across northern mexico. The GFS and the canadian are wetter solutions as they drag the low pressure across the rio grande and south texas late in the weekend. The ECMWF is the drier of the solutions. Despite still maintaining the low pressure feature the 00z GFS did trend closer to the 00z ECMWF with less qpf. Will continue to lean towards the drier ECMWF which maintains 20 to 30 percent pops for the weekend across much of the area. Regardless of the rainfall coverage, the weakness of the ridge and potentially increased cloud cover will keep afternoon highs for Saturday into early next week close to normal for the latter half of august. While models do show the ridge strengthening early next week, the center of the ridge will be over oklahoma and north texas rather than south and west texas. This keeps slight chance pops in the forecast due to increased moisture and potentially the upper level low still hanging around south texas as an inverted trough. While it is good to see rain chances in the forecast not everyone will see rain over the next 7 days as coverage will generally be isolated.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
